A) Hydro fluosilicic acid
B) silica gel
C) silicic acid
D) calcium fluorosilicate
Correct Answer: D
Solution :
\[2Ca{{F}_{2}}+Si{{O}_{2}}+{{H}_{2}}S{{O}_{4}}\xrightarrow[{}]{{}}Si{{F}_{4}}+{{H}_{2}}O+CaS{{o}_{4}}\]\[\xrightarrow[{}]{hydrolysis}CaSi{{F}_{6}}\]You need to login to perform this action.
